The Beretta A300 Ultima Patrol 12 Gauge 19.1 in Black 7 + 1 is a duty-ready semi-auto shotgun that redefines what a tactical scattergun can do. It’s built on Beretta’s proven A300 gas-operated platform, then optimized for defensive use with a 19.1-inch barrel, extended tube magazine for 7+1 rounds of 3-inch shells, and oversized controls you can run hard under stress. This isn’t a hunting gun with a black coat of paint — it’s a purpose-built patrol tool with an M-LOK forend, QD sling points, and a 7-slot Picatinny rail ready for red dots or irons. If you’re a tech-forward shooter who wants a reliable, fast-handling 12-gauge that keeps up with modern accessories, the A300 Ultima Patrol is your next platform.

Key Features
- Extended Magazine Tube (7+1 capacity) — Gives you two more rounds than a standard 5+1 tube, meaning fewer reloads under duress and more firepower when seconds count.
- M-LOK Forend with QD Sling Points — Lets you mount lights, lasers, or grips directly to the forend without adapters, and the flush QD cups make sling attachment instant and low-profile.
- 7-Slot Picatinny Rail — Accepts any micro red dot, holographic sight, or backup iron sight set without a gunsmith, so you can transition from bead to dot in minutes.
- Enlarged Bolt Release, Safety, and Charging Handle — Oversized controls are easy to manipulate with gloves or under adrenaline, reducing fumbles during reloads or clearing malfunctions.
- Gas-Operated Semi-Auto Action — Beretta’s self-cleaning piston system cycles light target loads and heavy 3-inch magnums reliably, with reduced recoil compared to fixed-breech designs.
Who It’s For
This shotgun fits the early-adopter shooter who wants a factory-ready defensive scattergun with modern attachment standards. It’s for the person who already runs an AR with M-LOK and a red dot and expects the same modularity from a shotgun. It’s for the three-gun competitor who needs a reliable 12-gauge that can take a beating and still cycle birdshot. And it’s for the home defender who wants a semi-auto that doesn’t require a trip to the gunsmith to mount a light and sling.
Pros / Cons
- ✅ Pro: Factory M-LOK and Picatinny mean no adapter plates or drilling.
- ✅ Pro: 7+1 capacity from a compact 19.1-inch barrel.
- ✅ Pro: Gas system tames recoil and runs dirty without cleaning.
- ❌ Con: The factory stock lacks an adjustable length of pull — taller or armored shooters may need an aftermarket stock or spacer kit for proper fit.
Comparison: Beretta A300 Ultima Patrol vs. Competitors
| Feature | Beretta A300 Ultima Patrol | Mossberg 940 Pro Tactical | Benelli M4 |
|---|---|---|---|
| Capacity | 7+1 | 7+1 | 5+1 (7+1 with tube extension) |
| Barrel Length | 19.1 in | 18.5 in | 18.5 in |
| Rail System | M-LOK forend + 7-slot Picatinny | M-LOK forend + Picatinny | Proprietary handguard |
| Weight (empty) | 7.2 lbs | 7.4 lbs | 8.4 lbs |

According to Beretta specs, the A300 Ultima Patrol weighs just 7.2 pounds empty — that’s lighter than the Benelli M4 by over a pound — while still offering a factory M-LOK forend and 7+1 capacity at roughly half the price. The Mossberg 940 Pro Tactical is a close competitor, but the Beretta’s gas system has a longer track record of reliability with light loads.
Is the Beretta A300 Ultima Patrol optics-ready out of the box?
Yes — it comes with a factory 7-slot Picatinny rail on the receiver, so you can mount any micro red dot, reflex sight, or full-size optic without any adapter or drilling.
Can it cycle low-recoil or target loads reliably?
Yes. The Beretta gas system is self-regulating and cycles everything from 1-ounce target loads to 3-inch magnum buck and slug loads without adjustment. It’s known for reliable function with light loads even during break-in.
What is the magazine tube capacity in the box?
The Beretta A300 Ultima Patrol ships with an extended magazine tube that holds 7 rounds of 2.75-inch shells. With one in the chamber, you get 7+1 total capacity.
Does the forend accept standard M-LOK accessories?
Yes — the forend has M-LOK slots on three sides (left, right, and bottom) so you can mount lights, vertical grips, or hand stops directly without adapters.
Is this shotgun compatible with 3-inch shells?
Yes — the chamber accepts 3-inch shells, so you can run high-velocity buckshot, slugs, or magnum waterfowl loads. The gas system handles the extra pressure without issue.
